What you are getting

A 2 m drinking-water supply hose with a PE inner and a stainless steel 1.4301 braid, DN8 with an 8.3 mm bore, a 3/8 in union nut at one end and a 3/8 in male thread at the other, rated to 10 bar at 20 °C and a maximum operating temperature of 90 °C, DVGW certified with KTW-A and W270 approvals. Made in Germany.

Three figures nothing else here gives

8.3 mm bore. The internal diameter, which is what actually limits flow. Cheap hoses are narrow inside and quietly throttle a good tap.

10 bar at 20 °C. A pressure with its temperature. Materials weaken as they warm, so a bar figure alone is not a specification.

90 °C maximum. The hot side, stated separately.

The certifications, named

DVGW, with KTW-A and W270. Material approval for drinking water contact, and resistance to microbial growth in the material itself. Both named rather than implied.

Check the ends

One end is a union nut, the other a male thread. That is not the arrangement of the other hoses in this hub, which are union at both ends.

Look at your tap tail and your valve outlet before ordering, and if you need union-to-union, three other hoses in this hub are.

Why the price

Roughly three times the cheapest hose here — and it is the one part in a bathroom whose failure empties the mains into your floor for as long as nobody is home.

Availability

On sale from 23 € to 35 € on the German and French Amazon stores at the time of checking.

The Italian and Spanish Amazon listings are priced above 1.6× the cheapest store, which is normally a reshipping offer rather than a local price; they are left out of the range above.

Listed but with no offer on the British Amazon store — the reference exists there and nobody is currently selling it.

Not found on the American Amazon store, where the buy link falls back to a local search rather than to a page that does not exist.

Prices and availability are what Keepa reported on the date this page was updated; both move.

    tecuro 300 mm flexible hose with a 90° bend, KTW-A and DVGW W270

    A short certified hose with a right-angle bend, and both a pressure and a temperature rating — which almost no supply hose publishes.

    Length
    300 mm — stated in the maker's own feature list; the title of the same listing says "300 m", which is evidently a typographical error
    End fittings
    Two 3/8 in union nuts (14.95 mm) in nickel-plated brass with a pressed-in seal, one end at 90° — stated
    Inner diameter
    Not stated as a figure — the inner hose is HDPE

    B00IN0OG68 (same reference on 5 Amazon marketplaces)
    EAN
    4260288371919
    • Publishes a pressure rating AND a temperature range, which most supply hoses do not
    • Certified to KTW-A and DVGW W270 — named drinking-water standards rather than a claim
    • The listing title says "300 m" where its own feature list says 300 mm — read the feature list

    Best for: A short, tight connection behind a pedestal basin where a straight hose would have to curve too sharply.

    • No pressure rating at all, on the component whose failure floods a room

    Best for: Connecting a 1/2 in tap tail to a 3/8 in angle valve, or the reverse, without stacking adapters.
